In MARC: Record as a structured description using field 300 subfield $a. If deemed useful for identification or selection, provide additional clarifying information as an unstructured description in a 500 note.
For notated music resources consisting of multiple formats (e.g, score and parts), either record all units of extent in a single 300 field or as separate instances of the element in multiple 300 fields. If the units are of significantly different sizes, prefer separate 300 fields.
See examples in MARC format: extent of manifestation . For related examples see also: Describing a manifestation .
Recording an unstructured description
Condition Option
In MARC: Generally do not apply the option in field 300 in a shared cataloging environment; if needed, provide details in a Manifestation: note on manifestation instead.

Instead, either record them together as a single value separated by a plus sign (+) and spaces, e.g. 1 score + 4 parts, or record the extent of each type of unit as a separate instance of the element. Follow the option for sets of parts and do not supply page count for parts. Otherwise record subunits as the option instructs.

For loose unfolded sheets, record the number of subunits for notated music on numbered sheets in terms of leaves if only one side is numbered or pages if both sides are numbered. If the sheets are unnumbered, record the number of subunits in terms of unnumbered leaves if there is printing on one side or unnumbered pages if there is printing on both sides.
